## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability defi-lending-liquidations-scanner-57539eff
```

Example prompt: Can you pull the last 6 hours of liquidation events on Aave v3 for me?

## When to prefer this

Use this endpoint when you need on-demand liquidation event data from DeFi lending protocols like Aave v3 with configurable time windows, and are willing to pay a small USDC micropayment per query. Prefer this over free alternatives when you need reliable, structured JSON output gated by x402 payment rails.

## Known failure modes

- Invalid or unsupported protocol value returns an error
- Window parameter exceeding ~12h may be rejected or clamped
- Payment failure (USDC not sent or insufficient) returns HTTP 402
- Malformed query parameters return a validation error
- Upstream protocol data unavailable may return empty result set

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

A JSON object with a `success` boolean and a `result` object containing liquidation events or at-risk positions from the specified lending protocol and time window.
